swift3 - Value of "String" has no member 'indices' - moving to Swift 3.0 -


i'm moving swift 2 (probably, 2.3) 3.0 , have hard time correcting following code : now, know string not collection anymore. how correct particular code?

let separator = anyword.indexof("-")!  anyword.substring(with: (anyword.indices.suffix(from: anyword.index(anyword.startindex, offsetby: separator + 1))))

as possible improvement @dfri's first solution, use upperbound of string's range(of:) method (which bridged nsstring) – give index after (first occurrence of the) dash in string.

import foundation  let anyword = "foo-bar"  if let separator = anyword.range(of: "-")?.upperbound {     let bar = anyword.substring(from: separator)     print(bar) // bar }

or compacted crazy single binding using optional's map(_:) method:

if let bar = (anyword.range(of: "-")?.upperbound).map(anyword.substring(from:)) {     print(bar) // bar }

although note general solution problem of 'string not being collection anymore', use string.characters instead, is collection.

iOS: Performance of reloading UIImage(name:...) -

i have tableview , each row has icon. 90% of rows have same icon. in cellforrowatindexpath method load image assets folder this: var cellimage = uiimage(named: "myimage") does pose performance problem? os somehow smart enough it's same image each time? better if loaded image once , saved in class variable , assigned each time? uiimage 's named: api does kind of caching. if @ uiimage's documentation , states: use init(named:in:compatiblewith:) method (or init(named:) method) create image image asset or image file located in app’s main bundle (or other known bundle). because these methods cache image data automatically, recommended images use frequently.

How to prevent logback from emitting repeated "Empty watch file list. Disabling" messages -

i have logback configured logback.xml located here: http://pastebin.com/kuquekxy . every minute, see log message emitted of form: 18:26:21,486 |-info in reconfigureonchangetask(born:1478715201485) - empty watch file list. disabling why happening , how can rid of these? i can tell why happening, not how rid of them. the reconfigureonchangetask log line when doesn't have files watch. and doesn't have files watch because file in jar, , only watch files on filesystem . makes sense, because files within jar file don't change.
